Writing a foreign data wrapper

Experiences with Informix

Writing a foreign data wrapper (FDW) for PostgreSQL seems easy. However, there are many pitfalls.

This talk will cover experiences from writing a FDW for Informix and will discuss problems with client libraries, data type mapping, optimizer support and performance related topics. Interested attendees will get a short overview on what they can expect from a FDW and (hopefully) learn something to do it better ;)
